[LEDE-DEV] [PATCH] bcm53xx: fix LAN MAC address for devices that use eth2 originally

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

We override default Ethernet interface with eth0 which often uses random
MAC due to missing proper NVRAM entry. Fix this by manually assigning
MAC in the config.
